Press ctrl+B in sublime to call python3 to run

Write the complete python3.exe path under the windows system.

The following is the operation of macOS, which is similar to that of windows.

Written the code for python3 using sublime text, but ctrl B called python2 when running, causing an error to be reported.

This is because many systems have python2 installed by default, and the default version of python called is python2.

Solution:

Let’s first create a new sublime build system

and then automatically open a text , clear and write the following content:

{
    "env": {"PYTHONIOENCODING": "utf8"},
    "cmd": ["/Library/Frameworks/Python.framework/Versions/3.6/bin/python3", "-u", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

"env": {"PYTHONIOENCODING": "utf8"}, to avoid Chinese errors!

[“/Library/Frameworks/Python.framework/Versions/3.6/bin/python3”, “-u”, “$file”], the path here should be replaced with the path of python3 in your computer.

Check the path of python3

$ which python3
/Library/Frameworks/Python.framework/Versions/3.6/bin/python3

Then, save the file name as python3.sublime-build

Then, select python3

Let’s verify the following, whether the current version is python3

import sys
print(sys.version)

Press ctrl B to run, the results are as follows

3.6.3 (v3.6.3:2c5fed86e0, Oct  3 2017, 00:32:08) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)]
